STDFLTR_ALPHA only?

We've got STDFLTR_ALPHA. It's defined as
public constant STDFLTR_ALPHA = routine_id("filter_alpha")
where filter_alpha is defined as
function filter_alpha(object elem, object ud) return t_alpha(elem) end function
and t_alpha as
public type t_alpha(object test_data) return char_test(test_data, Defined_Sets[CS_Alphabetic]) end type
There are other cool t_* out there like t_digit and t_cntrl but they don't have STDFLTR_*. Deliberate? Accidental? An exercise for the programmer?
